With current field applications of GWB, it should be clear the expected shear resistance capacity of a typical exterior sheathed wall with an interior GWB applied does not meet the capacity expected by the IRC or SDPWS. Concealed flange hangers have the face flanges turned in. When using these screws on wood to wood connections, or in other applications where the screw will pass through wood first, it is advisable to use a washer with the screw so that the head won't crush the wood and reduce the load handing capacity. screws located at least 2" but less than 6" from the end, use 50% of the load per screw and 50% of the table spacing between the end screw and the adjacent screw, and for screws located between 2" and 4" from the end, predrill using a 5⁄32" drill.

CA Residents: Prop 65 WARNING (S) Length (Inches) Maximum Extended Length (Inches) Manufacturer Color/Finish. The large washer head gives high head pull-through resistance while allowing the timber members to close up firmly. Various types of screws ranging in sizes between No. Stainless Steel & Stainless Steel Fasteners Chemical, Physical and Mechanical Properties Stainless steel describes a family of steels highly resistant to tarnishing and rusting that contain at least two separate elements alloyed together. Only the capacity based on the fasteners themselves is computed: neither the wood elements themselves, nor any steel side plates specified, are checked for strength or serviceability. Both lateral (single and double shear) and withdrawal capacities can be determined. Here we display a specific beam loading case. Shear values for 5/8" gypsum board exceed those for ½" gypsum board, 4. Introduction In the manufactured housing industry, one of the principle uses of lag screws is the connection of the wood-frame house to the transportation chassis. Material: See table Finish: Galvanized Installation: Use all specified fasteners (included). At that length, the screw extends into the adjoining board by 1/2" (1 1/4 – 3/4 = 1/2). One 2″ x 4″ x 8′ #2 Spruce Pine Stud is good for about 3000 lbs of compressive load, when held in place by drywall.
